Subject: command: playlistinfo now uses a range argument rather than just a
song id
Loosely based on a patch provided by lesion in bug #1766. The playlistinfo
command can now retrieve ranges of the playlist. The new argument indicates
which entry is the last one that will be displayed. The number of displayed
entries may be smaller than expected if the end of the playlist is reached.
Previous usage:
playlistinfo [start]
New usage:
playlistinfo [start[:end]]
